The Pattern Formation problem is one of the most important coordination problem for robotic systems. Initially the entities are in arbitrary positions; within finite time they must arrange themselves in the space so to form a pattern given in input. In this chapter, we will mainly deal with the problem in the OBLOT model.

Pattern Formation in Mesic Savannas. [PDF]
AbstractWe analyze a spatially extended version of a well-known model of forest-savanna dynamics, which presents as a system of nonlinear partial integro-differential equations, and study necessary conditions for pattern-forming bifurcations. Homogeneous solutions dominate the dynamics of the standard forest-savanna model, regardless of the length ...

Pattern formation in semiconductors [PDF]
In semiconductors, nonlinear generation and recombination processes of free carriers and nonlinear charge transport can give rise to non-equilibrium phase transitions. At low temperatures, the basic nonlinearity is due to the autocatalytic generation of free carriers by impact ionization of shallow impurities.

Dentritic Pattern Formation [PDF]
We present a numerical analysis of dendritic crystal growth. The growth of dendritic crystals occurs when the relevant transport of heat or matter takes place in the medium ahead of the advancing interface, such that the crystallization front moves into a supercooled or supersaturated region.

Cell Sorting daring Pattern Formation in Dictyostelium [PDF]
Formation of the prestalk-prespore pattern in Dictyostelium was investigated in slugs and submerged clumps of cells. Prestalk and prespore cells were identified by staining with vital dyes, which are shown to be stable cell markers.

Characteristics of pattern formation and evolution in approximations of physarum transport networks [PDF]
Most studies of pattern formation place particular emphasis on its role in the development of complex multicellular body plans. In simpler organisms, however, pattern formation is intrinsic to growth and behavior.

Laplacian Pattern Formation [PDF]
The formation of snowflakes, viscous fingers and electrodeposits is governed by analogous equations : these structures are all Laplacian patterns. In this paper we review model experiments and computer simulations which are widely used to study diverse morphologies resulting from the motion of unstable interfaces.
